Ignition Rotor: Description and Operation

Rotor Resistance:

The resistor rotor is mounted to the front of the camshaft via the rotor adapter. The distributor cap and rotor are set so that when an ignition impulse is generated by the coil, the rotor points to the appropriate terminal of the distributor cap and the ignition energy is directed to the correct cylinder through the ignition wires. A 1K ohm resistor is molded into the rotor for radio frequency suppression.
